Inliners International Forums General Discussion Engines Head Bolt Washer

I don't believe any Chevy engine from that era ever used a washer on the head bolts. Washers for this type of application are from modern era engines where the washer acts to provide some sort of clearance and may also include an upward facing chamfer that mates with a radius ridge machined into the bolt. I believe washers are universal when head bolts are replaced with studs.
